You can use JavaScript's fetch API to retrieve data from external sources. Here's an example:

async function getData() {
 const res = await fetch('https://api.example.com/data');
 const data = await res.json();
 return data;
}

This function asynchronously fetches JSON data from the specified URL.

Once you have fetched the data, you can display it in your MDX content using JSX. For example:

import { useState, useEffect } from 'react';


function DataDisplay() {
 const [data, setData] = useState(null);


 useEffect(() => {
 async function fetchData() {
 const result = await getData();
 setData(result);
 }
 fetchData();
 }, []);


 if (!data) {
 return <p>Loading...</p>;
 }


 return (
 <ul>
 {data.map((item) => (
 <li key={item.id}>{item.name}</li>
 ))}
 </ul>
 );
}


export default DataDisplay;

This component fetches data and renders a list of items.

You can import and use the DataDisplay component in your MDX file:

import DataDisplay from './DataDisplay';


<DataDisplay />

This will render the fetched data within your MDX document.

# Integrating and Utilizing Data Inside MDX


This document demonstrates techniques for acquiring and showing data directly inside your MDX files, all while utilizing the capabilities of JavaScript.


## Data Acquisition


Employ JavaScript's `fetch` API to pull data from external locations. An illustration follows:


```javascript
async function getData() {
 const response = await fetch('https://api.example.com/data');
 const jsonData = await response.json();
 return jsonData;
}

This asynchronous function retrieves JSON-formatted data from a designated web address.

After retrieving data, present it within your MDX document using JSX syntax. Consider this example:

import { useState, useEffect } from 'react';


function DataDisplay() {
 const [dataHolder, setDataHolder] = useState(null);


 useEffect(() => {
 async function fetchData() {
 const outcome = await getData();
 setDataHolder(outcome);
 }
 fetchData();
 }, []);


 if (!dataHolder) {
 return <p>Content Loading...</p>;
 }


 return (
 <ul>
 {dataHolder.map((element) => (
 <li key={element.id}>{element.name}</li>
 ))}
 </ul>
 );
}


export default DataDisplay;

This React component gets data and then displays a list of the received items.

Incorporate and utilize the DataDisplay component inside your MDX file like this:

import DataDisplay from './DataDisplay';


<DataDisplay>

This inclusion will render the received data directly into your MDX content.
